Abstract
Mathematical formulas relating focal-spot separation to various geometric factors in magnification radiography are presented. Focal-spot separation is closely related to the magnification factor, focal-spot/film distance, viewing distance, and object size. When the viewing distance is equal to the focal-spot/film distance, separation is inversely proportional to magnification.Keywords
